I mean from an evolutionary genetic viewpoint, what is the point of light skin in northern lattitudes? I can understand how natural selection would favour darker skin nearer the equator because light skin is useless against harsh UV rays etc. But why would natural selection favour lighter skin in the more northern lattitudes, its not like it protects your from the cold or anything. And also for humans it wouldn't serve as camoflauge because we don't flaunt around nekkid. Why did nature favour that baleful mutation that turned skin albino pasty white and useless against direct sunlight?

I don't know, it doesn't look as healthy. I'm in pretty good shape but i'm a naturally snowy white Caucasian so it goes to waste. Mediterranean skinned people have a better color. It looks healthier. I'm stuck with Irish skin, so i hardly can even tan if i'm out all summer. But I don't burn, so I'm better off then most of my whitey kindreds.

there really isnt any as far as i can come up with
even arctic animals have dark skin so they can absorb what little sunlight they get for maximum energy efficiency

I hope this isnt serious but anyway what the hell..

The idea of melanin is to protect your skin from dangerous high UV rays near the equator, it blocks UV rays from causing damage.

If you have dark skin in low light/UV areas, like in northern Europe, where some places have very little sunlight, you NEED your skin to absorb as much UV rays as possible, otherwise you will be Vitamin D deficient, which causes all sorts of health problems. So having high amounts of melanin (pigmentation) is not needed, or valuable.

Humans must have needed a whole LOT of vitamin D for nature to allow only albinos to survive.

Did I not just explain to you how having white skin is alot more "fitted to nature" when living in low sunlight conditions? Do you not understand it was Nature itself that controls everything in an organism?

Nature allowed Humans out of Africa to live in lower strength sunlight area by decreasing the amount of Melanin in their skin, therefore allowed vitamins produced in the body from sunlight to be produced that without, would otherwise cause defects (especially bone defects) that would seriously hinder survival.

Am I not being clear enough, or are you just the worst secondary yet and why hasnt Pro banned you?

henri, don't pay him any attention. he was so ashamed of his pasty burning flesh that he told everyone here he was darker than wesley snipes.




yeah cause obviously people who don't live near the equator and hot weather become albino.

They live in high UV conditions, and in snow, which reflects sunlight.

Snow reflects UV rays, causing you to burn very very fast (anyone whos been skiiing knows this). So more melanin would be beneficial.

and then you know, south africans and southern argetinians are white as ghosts.

not to mention the chinese that are on the same latitude and in the same geographic conditions as euros. they are milky.

you hate yourself. shut up.
its bad when your skin is whiter than your teef.
and you said you were black.

Ok makes sense

No I don't know.

So more melanin would be beneficial.

If you use that logic then wouldn't that mean that more melanin would be beneficial for northern europeans as well? I don't think there is a lot of difference in UV intensity maybe even more in europe. And even in your own element, don't you STILL get sunburns on the reg'lar during the summer?

No actually there isnt as much, no. The fact you just compared Belgium, Holland, Switzerland (countries who for most of the year have no snow whatsoever) etc with Arctic conditions eskimo's face with year round means I should really end the debate right here LOL.

and then you know, south africans and southern argetinians are white as ghosts.

These people migrated to these countries only in the last few hundred years you fucking moron. We're talking 100,000's of years for skin pigment changes.

not to mention the chinese that are on the same latitude and in the same geographic conditions as euros. they are milky.

Your general lack of human evolutionary history and origins is quite sad for someone who is so vitriolic in his beliefs. You arguments are all redundent and pretty sad dude.

you hate yourself. shut up.
its bad when your skin is whiter than your teef.
and you said you were black. Er, not quite. I see recently youve taken to lying alot, in a desperate last grasp of keeping hold of sanity in the face of another breakdown. I do however have a mixed family, if it puts your mind to rest.

OK i'll give a better explanation for Inuit. My last one wasnt quite right. first of all Eskimos are descendents of meso-american peoples who migrated up the americas, this is where there skin tone comes from originally.

As I mentioned before, UV rays provide the body with much needed Vitamin D, though the skin. However, the Inuit, who also dont have much exposure to sunlight, are not as dependant on UV rays to provide them with Vitamin D, as their diet is very high in fish, which is a Vitamin D rich food, which kept them from developing less melanin.

So lets clarify this:

Blacks are the original man and have dark skin like their ape cousins :) they keep the skin designed for their climate. Ie. Chimps are actually black skinned not pussy human black skin.

We then moved out of Africa through the Saudi peninsula into Europe and Asia. We then developed somewhat lighter bronze and brown Mediterranean and Semitic skin tones. These need some more vitamins because theres less light in that region. As we headed north the light lessened more so and we got Caucasian skin tones.

Asians are in the same boat. Northern asians are much paler then equatorial asians and pacific islanders. Look at the difference between Japanese people who are lighter skinned and Indonesians. They're all asian but their skin varies. Same shit with native americans and that's everybody. That's why Australians are black even though they aren't African.

Next question: I know that Africans have broader features because its useful in a hot wet environment and that Narrower noses are better in dryer climates or something, but why do asians have their features. Why aren't Asians white looking?

The Asian evolutionary line is still a very hot topic of debate and has multiple lines of theories. But Asia has the one of the wettest and humid climates on Earth, I'm not saying that means anything, but as you said narrow noses are better for dryer condtitions etc..

Also, Japanese are actually pretty pale on average, especially compared to Han chinese. And you cant really just take things on face value, say in a place like China, because there couldve been a rapid expansion of a certain "race" for other reasons other than evolutionary, like wars and culture. But the studies says it takes minimum of 500 years of ancestry for noticeable changes in melanin.

But as somone whos travelled Asia and experianced the climate, the skin tones are what I would actually expect for each region, almost perfectly. The hotter the place, the darker the people are. Not rocket science.

Are you out of your fucking mind. All the great apes have lighter skin because their entire bodies are covered up by fur.

Good question. I'll ponder over this throughout the next few hours.

I know the Japanese are paler then the Han, that's because their ancestors came from what's Russia I'm pretty sure, may be wrong. But why the "chinky" characteristics?

What do the squinty baggy eyes do for them?

But seriously, read here > http://en.wikipedia.org/wiki/Epicanthal_fold

They have the same eyes, they just have a different eyelid fold, which give that appearence. That page explains why a human might evolve that type of eye in the part of the world.

Jesus Gavin, you're trying that shit out again?

Remember all those times in KTL where i set you straight?

Obviously your pineal gland has started to override the rest of your brain once again.

Thankfully Lacey is doing enough to explain away your questions, so i don't have to.

But really, you and those like you always try that Inuit + Polar Bear shit.

It's pathetic and so easily explained, and i've done it many times before.

My question is, why do you submit yourself to such easy ether?

You fucking idiot.

Why didn't you say "and then, ya know, the Australian's are as white as ghosts!!!! But like, the Aboriginal people aren't!!!". "White american's are white as ghosts!!! Why aren't native american's!!!!!!??????"

I think all that time you're spending rubbing up against skampoe is having a seriously detrimental effect on your brain.

You were stupid before, really stupid.

But i can't remember it being this bad.

As long as you can see something with either your eye or with some an instrument - It means Its "whiter" than black.

I heard that the reason black people have dark skin in hot enviroments is because like stated previously it protects against uv rays and also black skin, does not retain heat but gets rid of it quickly...and the reason white people have pale skin in cold enviroments is because there is less uv exposure and also because white skin retains heat which would be more practical in cold waether.


Which leads me to a question that I have been pondering...if blacks need dark skin to protect from hot climate will the blacks in say america or the u.k who have moved and live in a colder climate, will they eventually over time slowly lose there dark skin as the generations pass and eventually become white because there will be no need anymore for them to have really black skin because the climate is not really hot like africa.


always wondered this ?????
